CAR TRUCK.

Application filed .Tune 2, 1922, Serial lvly invention relates to car trucks and more particularly to a type ot truckv wherein the side trame members on opposite sides ot the trnclc; are cormectcd in a nninncr pern'iittingl them to execute a yieldingly resisted relative movement longitudinall.)r of the truck4` thereby iii,ininilizinp` the shocks and strains t 'ansmtted to the structure incident to its passage around cari 9, over switch points or because ot irregularities in the track or the truck wheels.

An object oit the invention, generallyv stated, is to providesimple, durable and elffective u'ieans ttor yieldingly inaintainingI the truck in square relation.y said means including' yieldingi'lv separable complementary cross members coi1nectinl the side iframes ot the truck, and a yielding device tor absorbingand cushioningl the blows or shocks incident todisplacei'nentr said vieldable device acting to impart restoration movement te the side frames tor returning' them to normal position.

More particularly stated. the principal object ot the invention is to provide a cross member in the foral ot a spring plank coinposed ot separable complementary sections each ot which is connected at one end to the respective trames and held rikiridly therewitli, and means vieldinnly connecting said comipnlementary sections. said means 'involving` a plurality ot spaced spring devices capable ot being energized troni either end and arranged tor operation siniultaneonsly when said complenientarv sections separate or move toward each other npon relative longitudinal 'mo'venlent oi' the side trame members.

Another object ot the invention is to provide a truclr lnivnp; side trame members joined together by relatively associated rigid and y able means permittlngI relative longitudinal movement ot the side trame members without sivin of of the eide trame connecting means. the ieldable port-ion of said means beine; adapted to restore the side trames to nori'nal position upon cessation of the torres prodnciino displacement :novezncnl.

A tintlier object ot the invention is to provide a plurality oli linigritudinallv arranged yi eldabl e devices connectin relatively lend-iiinlinallv movable connilementerv sections ot' a cross member. said .vieldable devices being adapted to be operated 'from each No. 565,319.

ln the preterred form oi my invention illnstreted in the drawings in which corresponding ret'ere ce characters designate Similar views in the several parts, the truck l is provided with the usual journal boxes, truck axles, brake shoes, and brake beams shown in dotted lines in Figure l. 'lhese parts et the truck may be ot the ordinary construction and term no part of my present invention.

rl`he side Atranne members 2 are each provided with a bolster opening arranged between the columns 5) et the side trames, the means coimccting` said side 'trame members enti-ending into and held Within said openings and adapted to permit relatively longitudinal movenilent ot the side iframes.
